MORRIS DAVENPORT, OF ENGLISHTOWN, ASSIGNOR OE ONE-HALF TO CHARLES E. IAXTON, OF JAMESBUBG, NEW JERSEY.

WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 388,956, dated September 4, 1888.

Application filed July 16, 1867.

To aZZ whom it may concern:

Be it known that I, Monnls DAVENPORT, a citizen of the United States, and a resident of Englishtown, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in WasirBoilers, of which the following is a specification.

My invention relates to that class of washooilers having water-circulating tubes on the exterior, with the ends of the tubes connected to the body thereof.

Prior to my invention said exterior circulating-tnbes have been arranged in vertical planes and in operation conduct the circulating water in that direction from the lower to the upper part of the boiler.

The object of my invention is to conduct the circulating water in adirect-ion both vertically and horizontally of the boiler, thereby producing a more uniform distribution thereof; and to this cnd it consists, essentially, in arranging the circulating-tubes in inclined planes, as hereinafter more fully described, and illustrated in the accompanying drawings, in which- Figure 1 represents aside view of my boiler. Fig. 2 represents a partial side view and partial vertical section thereof. Fig. 3 represents an end view thereof. Fig. 4. represents a horizontal section thereof.

Similar letters of reference indicate corresponding parts.

The letter A represents the body of the boiler, having in this example an oblong shape in cross-seetion and provided with the usual lid,B,and handles a a, and G D are the watercirculating tubes, which are connected to said body in any suitable manner. Said tubes 0 D are arranged in inclined planes,as more clearly shown in Fig. 3; and in the present example of my invention the inclination thereof is in Serial No. 244,484. (No model.)

opposite directions, this arrangement being preferable when the boiler is of oblong shape, in order to bring the lower and upper ends, respectively, of the tubes on opposite sides of the boiler. In the present example, moreover, the lower and upper ends of either tube are in the horizontal plane of the corresponding ends of the other tube.

When the boiler is applied to use, the hot water therein circulates in the tubes 0 D in a well-known manner, and it will readily be seen that,due to the inclined position of said tubes, the water is thereby conducted in a direction bot-h Vertically and horizontally of the boiler, or, in other words, it is conducted not only from a lower to an upper part of the boiler, but also from side to side thereof, the effect of which is to produce a very uniform distribution of the water in or through the clothes in the boiler, the clothes acting as a diaphragm within the boiler between the lower and upper ends of the tubes to induce approximately horizontal currents in the water.

\Vhat I claim as new, and desire to secure by 6 Letters Patent, is

The combination, with a wash-boiler. of ex terior water-circulating tubes arranged in in clined planes for the purpose of conducting the circulating water in a direction both vertically and horizontally of the boiler, the ends of said tubes being connected to the body of the boiler, substantially as shown and de scribed.

Signed at Englishtown, in the county of Monmouth and State of New Jersey, this 22d day of June, A. D. 1887.

MORRIS DAVENPORT.
